The temperature of the flame is the same from start to finish because it is continually replaced. “The object” after 5 seconds and “the object” after 5 minutes, probably different. So now we need a timer.

But this thermometer measures temperature in the past.

People who work with metals can estimate the temperature of the sample by the color that it is glowing. That still doesn’t tell the flame temperature.
I believe that high temperature, like a flame or the sun can be measured by measuring the spectrum of the light being emitted.

Wasn’t talking about “in equilibrium” was talking about ice on one hand and steam on the other. The ice in your home freezer is <0 C. The next transition for steam is plasma and steam can get quite hot on the way to that.

That was the point.

Yes, you are right about that – exactly what I do without being too concerned about its accuracy. I have always loved this experiment and feel it may have been rather forgotten. It, of course, is less about the answer and more about the method and its limitations. Kids used to enjoy it!

Have a look at this one of mine https://youtu.be/u2f7Ib7KoYo and if you want to see how to determine the Latent Heat of Vaporisation of water and can bear a lesson of mine: https://youtu.be/rnyrsaU4Y-M
